Pendulums. Simple Harmonic Motion. Simple Harmonic Motion. Pendulums and Springs are very similar. They repeat the same cycle of motion over and over and over. This is called Simple Harmonic Motion. Amplitude = Displacement. Amplitude: How far away from the equilibrium position

Pendulums. almost follow Hooke ’ s law. § 13.6. Angular Oscillators. Angular Hooke ’ s law: t = – kq Angular Newton ’ s second law: t = I a So – kq = I a General Solution: q = Q cos( w t + f ) where w 2 = k / I ; Q and f are constants. Simple Pendulum. L. q. m.

Pendulums . By: Nahdir Austin Honors Physics Period 2 . History of the Pendelum. First used in the H an dynasty’s seismometer device by scientists Zhang Heng . T enth century Egyptian astronomer Ibn Yunis used a pendulum for time measurement.

Everything oscillate . even stars – but it takes some time – 1 oscillation per 70 million years. Oscillations. most solids are elastic - most material objects vibrate when given an impulse a boat at anchor at sea the human vocal chords an oscillating cantilever

Pendulums. 1602: Galileo's research Italian scientist Galileo Galilei was the first to study the properties of pendulums, beginning around 1602 .

Reminder: Bellworks were collected on Friday. Please hand yours in this morning if you haven’t already! Reggie graded and entered those that were turned in Friday. . Pendulums. Pendulums.

Pendulums. Starter. What is the equation that links time period, T, and frequency, f? T = 1 /f or f = 1 / T What affects the frequency of a simple pendulum? Mass, length, how much it swings? Just length! Why did grandfather clocks have pendulums?

Pendulums. 3.P.1.3 Explain the effect of earth’s gravity on the motion of any object on or near the earth. What is a Pendulum?. A pendulum is made of an object, called a bob that dangles from the end of a rod or string and swings freely. .
